Application tiled March 6, 1918. Serial It. @,406.

To all whom 'it may concern.

15e it known tliatI, PHILIPPE im CLAMECY, a citizen of the United Stat-es, and a resident. of Boston, count)T of Suffolk, and State of Massachusetts, have invented certain new and useful Improvenientsin Type-lviitin4 the plateny carriage rearwardly and down 1v within the main frame of the ma.

wart chine to a more compact position and out of operative relation with the keioperated levers, said separable part of the escapeiiient mechanism being adapted to move with the platen carriage from an inoperativepo sition and automatically placed into coperative relation with the other -part of said escapement mechanism to adapt the escapement mechanism to be operated and the letter-feed movement of the carriage controlled as the keys are depressed. v

Another object of the invention is to provide a 4typewrit-ingf machine wherein typebars and the escapement mechanism may be operated by y,twopart key-operated levers and the vescapenieiit Vmechanism only operated bv twojpart space bar levers, one i'part of which are follable relatively to another part. I l v Other obJects, of the invention are to proivide a tvpewriting' machine wherein' the Space bail' forms a part of a keyboard and is adapted to fold as a. part of the keyboard to a compact position: to provide means wherel'ivthe` space levers and key-operated levers may he' held to fold' and untold together: and to provide a tvpewr'itiiig machine in which the space har is foldahle and has a common axis .with foldahle parts of keyopcrated levers, and which space har ,is

adapted lo operate thc` universal liar inde- .pendentlv of the printing..r instrulnentalities. .l further olije'ctot 'the invention is to provide a typewriting machine .wherein the away.

carriage, tension mechanism and a part. of

the escapement mechanism may be given a vertical shift movement. A still further object of the invent-ion is Patented Sept. 17, 1918.

to provide a simple and. ellcient escapement release to adapt the carriage to move freely transversely of the machine.. With these and'otlier objects in view` the invention will be hereinafter more partielllarlyldescribed with reference to the' accompanving'drawings, which form a part of this application, and will then be pointed out in the claims at the end of the description.

At the forward portion of the ina-chine isa keyboard frame part 15. Thisl keyboard fi'aine part 15 isi-hinged at 1G to the inain frame partand atthe outer portion thereof may' be provided with rubber fret oftheusual kind. The lterhoard frame part is tray-like in forni and isadaptetl' to fold upwardly and inwardly'as show-adn 'dotted lines` in Fig. 1.

The `pin 71 is adapted to 'engagean aperture 74 in one :end of Vthe carriage bed or other-'part and lock said bed .to the vertically moving supporting member 50 'so ythat the platen carriage cannot fold rearwardlyuintil the -pin is released. The platen carriage may also be held against a.'

As an escapem'ent operating mechanism to control the letter-feed movement of the platen carriage and meansto operate said mechanism a universal bar 75 is provided, which is adapted to overlie the inner ends ot' the keyoperated levers This universal bar extends transversely of. the machine and has upwardly extending ends 76 which are lguided in tubular posts or guides l t. downwardly in the path4 of -the key-levers 23 by springs TS. The universal bar has inwardly extending arms 79 and these arms The unversal bar is normally forced extend upwardly, as at S0, at opposite sides of the machine. 'At the upper ends ofthe parts 80 are heads or slides 81 and S2. These heads S1 and S2 are suit-ably guided at their upper ends by brackets 83 or otherwise, and said heads are adapted to engage rollers S-l and Sa respectively, both of which are mounted upon a transversely movable rod S6. The rod 86 is suitably supported in the machine frame and is normally lforced against4 the action ofthe heads 81 and S2 by one or more springs 87. The heads 82 are each provided with a straight portion SS forming a normal seat for the .rolls 85 and a beveled or inclined part 88l forming a wedge-like actuating part on eachhead. Pv'otally held to each head is a pawl or dog S9. The pawls 89 have their free ends normally forced outwardly beyond the heads to provide Vteeth 90.-` andeach tooth is adapted to move inwardly within a recessed part'.
